 A.
Safety equipment is worn on all plots. This includes
head and eye protection. |
| B.
This precision, hand-held instrument is used to measure heights,
vertical angles and slopes. |
| C.
The increment borer is used to extract a core sample from
the site index trees. The core rings are either counted in
the field to age the trees or sent to a lab for analysis. |
| D.
Tally trees are marked at DBH for future reconciliation in
one of two ways: 1) thick barked trees are scribed into the
outer bark, and 2) thin barked trees are marked with permanent
ink. |
| E.
Stereo
photos are used to aid the field crew in establishing or relocating
a plot. Stereoscopes are used to view the aerial photos in
3D. |
| F.
Data recorders are used to electronically receive the plot
data while on the plot. The advantage of data recorders over
traditional paper tally is that the data recorders can be
programmed with edit checks, history data, and are weatherproof. |
| G.
The tatum is used to carry aerial photos and tally sheets.
At the plot, it is used as a writing surface and clip board. |
| H.
A variety of measuring tapes are used on the field plot. The
loggers tape has distance graduations on one side and diameter
on the other. The diameter tape is used to measure tree diameters.
The 100' cloth tape is used to measure distance from the starting
point to the plot center and to the subplots. |
| I.
GPS Data Collection is used to help
find new plot locations and establish the plot center. |
| J.
The compass is used to "shoot" a bearing from the starting
point to the plot center. Bearings are also recorded for individual
tally trees from plot center. |
| K.
The field vest is used to carry tools necessary to measure
and record data on the plot. There are special pockets for
the compass, clinometer, increment borer and pencils. |
